Innovative Liquid Metal Solution to Manage Heat in Fusion Reactors

Laboratory proposes lithium vapor 'cave' to protect tokamak interiors from extreme temperatures.

Researchers at PPPL suggest using evaporating liquid lithium to shield tokamak interiors from intense plasma heat.
Computer simulations identified the optimal placement for a lithium vapor 'cave' near the bottom of the tokamak by the center stack.
The 'cave' configuration simplifies the device design while effectively dissipating heat and protecting the core plasma.
An alternative method involves a capillary porous system to deliver liquid lithium directly to high-heat areas without major modifications.
These innovative approaches aim to advance fusion technology as a reliable power source for the future.
